How can law firms use WhatsApp Business API?

Law firms and advocates use WhatsApp Business API to remind clients of hearing dates and what to bring, share certified copies, orders and draft agreements, collect signed vakalatnamas and supporting documents, confirm consultation appointments and send fee notes, while keeping every client conversation on one chamber number. Bar Council rules restrict advertising, so promotional broadcasts are not appropriate.

Questions about WhatsApp Business API for law firms and advocates

Can advocates use WhatsApp for marketing in India?

No. Rule 36 of the Bar Council of India Rules prohibits advocates from soliciting work or advertising, beyond limited website information the Council permits. A law firm's WhatsApp number should serve existing clients with reminders, updates and documents, not broadcast offers to new people.

Is it safe to share legal documents on WhatsApp?

WhatsApp encrypts messages in transit, and the team inbox keeps documents on the chamber's number rather than staff phones. For highly sensitive matters, share a password-protected PDF or a secure link, and confirm the client's number before sending anything privileged.

Can clients send scanned documents and photos?

Yes. Clients can send photos and PDFs of deeds, notices and IDs in reply to a message or after writing to you. The clerk tags the chat with the matter number so documents are easy to find when drafting.

Can a hearing reminder be sent automatically?

Yes. If your case diary is in software or a Google Sheet, MsgClub can send the reminder a set number of days before each date. The template is a utility message because it concerns the client's own matter.

Should court updates go by WhatsApp or a call?

Routine next-date updates suit WhatsApp because the client has them in writing. Adverse orders, settlement offers and anything needing a decision deserve a call from the advocate first, followed by a written summary in the chat.

Can several advocates and clerks share one chamber number?

Yes. Each person gets a login to MsgClub's team inbox, and chats are assigned by matter. The senior can see every conversation, and the history stays with the chamber when a junior moves on.
